Abstract
In an object-oriented or object-based computer system, object methods are routed to users (e.g., client programs) after automatically performing supervisory functions. Examples of suitable supervisory functions include authorization checking and locking. One suitable way to automatically perform the supervisory functions is to provide a call method instruction in the operating system that automatically performs these supervisory functions when a user invokes the object method using the instruction. In this manner, the operating system can assure that the user calling the object method has sufficient authority and lock to access the object method. In addition, the method routing mechanism has the ability to forego authorization checking and locking for objects that are unprotected, and may perform abbreviated authorization checking and locking if the operating system determines from local knowledge that a user is currently authorized to and locked on the called object.
